Heatwaves Overwhelm Southern China's Power Grids.

Southern and eastern China are experiencing heatwaves that are expected to persist through June, with temperatures exceeding 40C in some areas. The high temperatures are putting power grids under strain as air conditioners are turned on full blast at homes, offices, and factories in mega-cities like Shanghai and Shenzhen. Demand for electricity in southern manufacturing hubs has surged, with China Southern Power Grid seeing peak power load exceeding 200 million kilowatts - weeks earlier than normal and close to historical highs.
